broken line or cutting debris from the spool area. (If you
plan to replace the spool or rewind it, this is the place to
do so, otherwise, move on.)
4. Unwrap about one foot (30 cm) of line to ensure that it's
undamaged. If it is OK rewind it and insert the line end

it drop into place. (When in place, the spool will turn a
few degrees left and right freely). Take care to keep the
line from becoming trapped under the spool.

few seconds or less you'll hear the nylon line being cut
automatically to the proper length.

CAUTION:
the cutting line protrudes beyond the trimming blade,
cut it off so that it just reaches the blade.
